Sleep deprivation (<or=5 hour per night) was associated with a higher risk of hypertension in middle-aged American adults but not among older individuals. However, the outcome was based on self-reported diagnosis of incident hypertension, and no gender-specific analyses were included. We examined cross-sectional and prospective associations of sleep duration with prevalent and incident hyperten...

The sleeping brain differs from the waking brain in its electrophysiological and molecular properties, including the expression of growth factors and immediate early genes (IEG). Sleep architecture and homeostatic regulation of sleep in neonates is distinct from that of adults. Hence, the present study addressed the question whether the unique homeostatic response to sleep deprivation in neonat...

BACKGROUND Chronic low back pain (CLBP) and chronic neck pain (CNP) have become a serious medical and socioeconomic problem in recent decades. Patients suffering from chronic pain seem to have a higher prevalence of sleep disorders. PURPOSE To calculate the prevalence of sleep deprivation in patients with CLBP and CNP and to evaluate the factors that may contribute to sleep impairment. METH...

conclusions using eye mask can significantly improve the sleep quality in cardiac patients. therefore, nurses are recommended to use eye mask in combination with current treatments for improving patients’ sleep quality. results after the study, the median scores of the subjective sleep quality, the sleep latency, the sleep duration, the habitual sleep efficiency, and the sleep disturbances doma...

introduction: sleep disturbance is common in patients undergoing coronary artery bypass graft surgery and has been recognized for more than 30 years. new literature suggests the importance of sleep and rest for restoration, protection and promotion of function and wellbeing of these patients. because of the importance of the role of nurses in diagnosis and treatment of sleep disorders, this stu...

Sedated sleep and sleep deprivation are commonly used methods to increase the diagnostic yield of the electroencephalogram (EEG), especially in the evaluation of people with epilepsy, but the rate of activation achieved by them is controversial, as is the issue of whether it is sleep itself, or sleep deprivation which is responsible for their alleged efficacy. We retrospectively studied the EEG...

While sleep loss is shown to have widespread effects on cognitive processes, little is known about the impact of sleep loss on emotion processes. In order to expand on previous behavioral and physiological findings on how sleep loss influences emotion processing, we administered positive, negative, and neutral affective visual stimuli to individuals after one night of sleep deprivation while si...

STUDY OBJECTIVES To evaluate the effects of a 25-hour sleep-deprivation episode on quantitative waking electroencephalogram (EEG) and subjective alertness in young and middle-aged subjects. DESIGN A 25-hour constant-routine protocol followed by a daytime recuperative sleep episode. SETTING Chronobiology laboratory. PARTICIPANTS Twenty-five normal subjects separated into 2 groups: young (a...

during adolescence, there is a tendency to sleep late and sleep less because of altered psychosocial and life-style changes. recent studies have demonstrated the link between sleeping less and gaining weight in children, adolescents, and adults. we studied the effect of late sleeping and sleeping less on body mass index (bmi) in medical college freshmen. all participants were adolescents (104 m...

OBJECTIVES Although several studies have shown that sleep deprivation is associated with increased slow wave sleep during the recovery night, the effects of sleep deprivation on cortisol and growth hormone (GH) secretion the next day and recovery night have not been assessed systematically. We hypothesized that increased slow wave sleep postsleep deprivation is associated with decreased cortiso...
